how to work out discounts - Step by Step

To calculate discount it is ease by using the following equations:

Now, let's solve the questions stated above:

1) What is 80 percent off $45? Find the amount of discount.

Suppose you have a Kohls coupon of $45 and you want to know how much you will save for an item if the discount is 80.


Replacing the given values in formula (a) we have:

Amount Saved = Original Price x Discount in Percent / 100. So,

Amount Saved = 45 x 80 / 100
Amount Saved = 3600 / 100
Amount Saved = $36 (answer).

In other words, a 80% discount for a item with original price of $45 is equal to $36 (Amount Saved).

Note that to find the amount saved, just multiply it by the percentage and divide by 100.

2) How much to pay for an item of $45 when discounted 80 percent (%)? What is item's sale price?

Suppose you have a L.L. Bean coupon of $45 and you want to know the final or sale price if the discount is 80 percent.

Using the formula (b) and replacing the given values:

Sale Price = Original Price - Amount Saved. So,

Sale Price = 45 - 36

Sale Price = $9 (answer).

This means the cost of the item to you is $9.

You will pay $9 for a item with original price of $45 when discounted 80%.

In this example, if you buy an item at $45 with 80% discount, you will pay 45 - 36 = $9.

3) 36 is what percent off $45?

Using the formula (b) and replacing given values:

Amount Saved = Original Price x Discount in Percent /100. So,

36 = 45 x Discount in Percent / 100
36 / 45 = Discount in Percent /100
100 x 36 / 45 = Discount in Percent
3600 / 45 = Discount in Percent, or

Discount in Percent = 80 (answer).
